Well, I don't know, but this game is a bit... too hard. All the stages are too unforgiving, and I'm stuck on the part after you get the weapon for 10 minutes straight now. Surely not a good use of my time. The wall bash is interesting. But it, in reality, is just wall-bounce that requires timing. And I couldn't even see what's behind me. I suggest toning the difficulty down a lil bit, or adding some new mechanisms. But since this is complete, that probably won't happen. It's a cool game, but sadly one I could not enjoy.
